Answer:
Multiply the first bracket by 3
Multiply the second bracket by -2
3x+3=-2x+2-4
3x+2x+3=-2x-2 negative (-) number and positive number (+)= negative number
Just rearranging
5x+3=-2
5x+3-3=-2-3
5x=-5
Dividing by 5
5x/5=-5/5
x=-1
Check answer by using substitution method
3(-1+1)=-2(-1-1)-4
0=-2(-2)-4 negative number and negative number = positive number
0=4-4
0=0
Answer is x=-1

Answer:
Option D.) x + 2x − 3 = 26
Step-by-step explanation:
Let
x ------> the length of Nate's car
y ------> the length of Maya's car
we know that
x+y=26 -----> equation A
y=2x-3 ----> equation B
substitute equation B in equation A and solve for x
x+(2x-3)=26
3x=26+3
x=29/3 in
Find the value of y
y=2(29/3)-3
y=(58/3)-3
y= 49/3 in
