Answer:
x = 7 (i think..)
Step-by-step explanation:
-3 (4 - 3x) = 5x + 16
* multiple -3 to each number in the parenthesis
-12 + 9x = 5x + 16
* add 12 to both sides to cancel it and combine like terms on the other side
9x = 5x + 28
* subtract 5x from both sides to cancel it out and combine like terms
4x = 28
* divide 4 from both sides to get x alone
x = 7
I'm pretty sure it's A, B, and D not 100% tho hope this helps!!
Answer:
Number 3 has no solution
Step-by-step explanation:
First you need to divide both sides of the equation 12x - 12y = -12 by 4
-3x + 3y = -3
12x - 12y = -12
-3x + 3y = -3
3x - 3y = -3
Then you need to eliminate one variable by adding the equations.
0 = -6
this statement is false, and therefore has no solution.
Answer:
12.25
Step-by-step explanation:
To find the c value in the equation, we need to divide b by two and then square it.
b= -7 and -7/2 is 3.5
Then we square 3.5 and we get 12.25
Number can be anything so lets call it x
