Question

can you help me with and have a explanation please thank you

Answer 1

Answer:

GIVEN -

• (-8z ) + 2 = 126
• 148= (-9y) - 5

TO FIND -

• Value of X and Y

SOLUTION -

- 8z + 2 = 126

-8z = 126 - 2

-8z = 124

z= $\frac{124}{-8}$

z=$\frac{ 62}{-4}$

z= $\frac{ 31}{-2}$

148= (-9y) - 5

148 + 5 = (-9y)

153 = (-9y)

$\frac{ 153}{-9}$. = y

-17 = y

More to know -

• This are linear equation in one variable which means it has degree one and have unique ( only one) solution.

• The line of linear equation is a straight line graphically.

Answer 2

Answer: z = 16    y = -17

Step-by-step explanation:

To solve z:

as this is an equation, do this to both sides

-8z + 2 = -126

-2:   -8z = -128

multiply by -1: 8z = 128

divide by 8: z = 16

how to find y:

As this is also and equation do this to both sides

148 = -9y - 5

+5:   153 = -9y

multiply by -1:   -153 = 9y

divide by 9:   -17 = y
