How do you solve equations with a variable on both sides x-2= -3x+2 i need to use algebra tiles to model and solve

To solve equations with variables on both sides, you must make the alike variables on one side, and the numbers on the other side. You do this by adding, subtracting multiplying, and dividing. Here are the steps to solve your problem:

x - 2 = -3x + 2   -- Add 2 to both sides

x = -3x + 4        -- Add 3x to both sides

4x = 4               -- Divide by 4

x = 1

Your answer is x = 1

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

so, converting firstly the mixed fractions to improper fractions and then "adding".
