Question

Use a bar model to solve each equation 1. x + 7 = 15 2. 19 = x + 13 3. 14.5 = 6 + y 4. a + 1/2 = 4 3/4 number 4 is a fraction

Answer 1

x=8

Explanation:

solve for x...so you'll want to isolate x and you do this, in this equation by subtracting 7 from both sides x+7-7=15-7. on the left side of the equation x+0=x and on the right side 15-7=8 so rewritten....x=8

2.

19=x+13

answer: x=6

3.

14.5=6+y

y=8.5

4.

a + 1/2=4 3/4

a=10
