Step-by-step explanation:

x + (-8x - 3) = 7

x -8x - 3 = 7

-7x = 10

x = -10/7

y = -8(-10/7) - 3

y = 80/7 - 3

y = 59/7

What is the value of a in the equation 5a -10b = 45 when b = 3

leva [86]

Salutations!

$5a-10b = 45$

value of $b = 3$

Multiply 10 and 3

$10*3=30$

Now, you can solve the equation --

$5a-30=45$

separate the variables aside, and the numbers aside.

$5a=45 +30$

$5a=75$

$a=75/5$

$a=15$

Hope I helped (:

Have a great day!
