Key Notes :<\/strong><\/p>\n\n\n\n

Like terms are terms that have the same variables raised to the same powers. To add like terms, add their coefficients.<\/p>\n\n\n\n

Learn with an example<\/p>\n\n\n\n

Solve for r<\/em>.<\/strong><\/p>\n\n\n\n

-5r<\/em> + 20r<\/em> + -20r<\/em> = 20<\/p>\n\n\n\n

r<\/em> = ______<\/p>\n<\/div><\/div>\n\n\n\n

Combine the r<\/em> terms:<\/p>\n\n\n\n

-5r<\/em><\/strong> + 20r<\/em><\/strong> + -20r<\/em><\/strong> = 20<\/p>\n\n\n\n

-5r = 20<\/p>\n\n\n\n

Divide by -5 to solve for r<\/em>:<\/p>\n\n\n\n

-5r \/ -5 = 20 \/ -5<\/p>\n\n\n\n

r = -4<\/p>\n\n\n\n

The answer is  -4<\/p>\n<\/div><\/div>\n\n\n\n

Solve for q<\/em>.<\/strong><\/p>\n\n\n\n

q + 11 \/ -3 = -1<\/p>\n\n\n\n

q<\/em> = _____<\/p>\n<\/div><\/div>\n\n\n\n

Solve.<\/p>\n\n\n\n

 q + 11 \/ -3 = -1<\/p>\n\n\n\n

q+11\/-3 . -3= \u2013<\/sup>1 \u00b7 \u2013<\/sup>3 Multiply both sides by \u2013<\/sup>3<\/p>\n\n\n\n

q<\/em> + 11 = 3 Simplify<\/p>\n\n\n\n

q<\/em> + 11 \u2212 11 = 3 \u2212 11 Subtract 11 from both sides<\/p>\n\n\n\n

q<\/em> = \u2013<\/sup>8 Simplify<\/p>\n<\/div><\/div>\n\n\n\n

\n
\n

Solve for u<\/em>.<\/strong><\/p>\n\n\n\n

2(u<\/em> + 9) \u2212 1 = 9<\/p>\n\n\n\n

u<\/em> =______<\/p>\n<\/div><\/div>\n\n\n\n

Solve.<\/p>\n\n\n\n

2(u<\/em> + 9) \u2212 1 = 9<\/p>\n\n\n\n

2(u<\/em> + 9) \u2212 1 + 1 = 9 + 1 Add 1 to both sides<\/p>\n\n\n\n

2(u<\/em> + 9) = 10 Simplify<\/p>\n\n\n\n

2(u+9)\/2=10\/2 Divide both sides by 2<\/p>\n\n\n\n

u<\/em> + 9 = 5 Simplify<\/p>\n\n\n\n

u<\/em> + 9 \u2212 9 = 5 \u2212 9 Subtract 9 from both sides<\/p>\n\n\n\n

u<\/em> = \u2013<\/sup>4 Simplify<\/p>\n<\/div><\/div>\n\n\n\n

Let’s practice!<\/strong><\/p>\n\n\n\n
