Answer:
(3,2)
Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13
Step-by-step explanation:
Consider the equation 4+2(5x - 8) = ax + b
Part A : for what values of a and b would the equation have infinitely many solutions?
Part B : if a = 10 and b = -4, explain how to find the number if solutions to the equation.

The value of x is -2
Step-by-step explanation:
Given that
6 (2x + 3) - 3(x - 2) = 6
Expand the bracket
6 (2x + 3) - 3(x - 2) = 6
12x + 18 - 3x + 6 = 6
Collect like terms
12x - 3x = 6 - 6 - 18
9x = -18
Divide through by 9
9x / 9 = -18 / 9
x = -2
Therefore, the value of x is -2
