5y + 3 > -7 + 13 how do i do this

ASHA 777 [7]

5y + 3 > -7 + 13

First add -7 + 13 = 6

5y + 3 > 6

Subtract 3 from both sides

5y + 3 -3 > 6 - 3

5y > 3

Divide both sides by 5

5y/5 > 3/5

y > 3/5

1) Find x, if 1/3 of x is 14

BartSMP [9]

"of" means multiply and "is" means equal

1. $\frac{1}{3}$ x = 14

x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>

x = 42

2. $\frac{1}{5}$ x = 14

x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>

x = 70

3. $\frac{2}{5}$ x = 14

2x = 14(5) <em>multiply both sides by 5 </em>

2x = 70

x = 35 <em>divide both sides by 2 to isolate "x"</em>

4. $\frac{7}{8}$ x = 14

7x = 14(8) <em>multiply both sides by 8 </em>

7x = 112

x = 16 <em>divide both sides by 7 to isolate "x"</em>

Answers: 42, 70, 35, 16
