3x + y = -3
Substitute y = x + 5 in the ‘y’ spot in the 3x + 7 = -3 equation
3x + y = -3
3x + x + 5 = -3
combine liked terms
4x + 5 = -3
-5 on both sides
4x = -8
/4 on both sides
x = -2
Answer:
x = -2
Answer:
The number is 
Step-by-step explanation:
Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.
Our number is z, then the left hand side of the equation is 9z-4.
The right side of the equation is 122. Then the complete equation is
. Add 4 in both sides to get
. Now, divide by 9 in both sides to get 
Equation:
6x + 3x = 45
To find X:
6x = 45
45/6 = 7.5
x = 7.5
To find other X:
3x = 45
45/3 = 15
x = 15
