Question

A) solve x + x + x = 54
b) solve y/5 = 7
c) solve 4t+6=24​

Answer 1

a) x = 18

b) y = 35

c) t = 4.5

Explanation:

a) x + x + x = 54

3x = 54

x = 54 ÷ 3

x = 18

b) y/5 = 7

(y/5) × 5 = 7 × 5

y = 35

c) 4t + 6 = 24

4t +6 - 6 = 24 -6

4t = 18

4t ÷ 4 = 18 ÷ 4

t = 4.5

Answer 2

a) 18

b) 35

c) -4.5

Explanation:

a) x + x + x = 54

combine like terms.

3x = 54

Divide both sides by 3.

x = 18

b) y / 5 = 7

Multiply both sides by 5.

y = 5 × 7

y = 35

c) 4t + 6 = 24

Take 6 to right side.

4t = 24 - 6

4t = -18

Divide both sides by 4.

t = -4.5
