Question

Solve the following equation when x = 7. y = 8 + 3x
HELP

Answer 1

Answer: Y = 29

Explanation:

We are given:

X = 7

Y = 8 + 3x

Since we know that the variable X is really the number 7, substitute it in...

Y = 8 + 3x

Y = 8 + 3(7)

Y = 8 + 21

Y = 29

Answer 2

y=29

Explanation:

Replace x with 7:

y=8+3(7)

Multiply 7 and 3:

y=8+21

Add together:

y=29
