2y + 7x + y-1?
y=4
-2y = 10 2y = -10 y = -5
well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
2y = 4 (divide both sides by 2 to solve) y = 2
Add 4x to each side: 2y = 4x + 8Divide each side by 2: y = 2x + 4
22
9+2y=3 2y=-6 y=-3
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
To solve the system of equations using elimination, first write the equations in a standard form. The equations given seem to be misformatted; if we assume they are (3x + 2y = 31) and (5x + 2y = 49), you can eliminate (2y) by subtracting the first equation from the second. This results in (2x = 18), so (x = 9). Substitute (x = 9) back into one of the original equations to find (y).
2y-3x=4
3x-2y=6 -2y=-3x+6 y=1.5x-3
