There is actually 2 ways to solve this, I will show you both.
The first is obvious, solve for x in the first one, and plug it into the 2nd one and get the answer
4x + 7 = 12
4x = 5
x =
8() + 3
2 * 5 + 3
10 + 3
13
The 2nd option is to manipulate the 4x + 7 to be 8x + 3
4x + 7 = 12
start by moving the 7 over
4x = 5
multiply both sides by 2
8x = 10
and add 3 to both sides
8x + 3 = 13
I’m going to go with Exponential
The second one is correct
Answer:
if you meant to put , then the answer is 7
Step-by-step explanation:
h=-2+32
solve for t
0=-2+32
subtract 32 from both sides
-32=-2
divide both sides by -2
16=
find suare root of 16
4= t-3
add 3 to both sides
7 = t
