Answer:
x = 5
y = 4
Step-by-step explanation:
just substitute the value of one variable into the other
-x +y = -1
or y = -1 +x <-------- (i just added x to the right side)
now u know what y is equal to, just substitute that value into the first equation
2x - (-1+x) = 6 <-------- instead of y, i put the value of y from the 2 equation
NOW SOLVE FOR X!
2x +1 -x = 6
x + 1 = 6
x = 5
now solve for y since you have the value of x
y = -1 + x
or y = -1 + 5
y = 4
Answer:
8x+1
Step-by-step explanation:
4(x-1) + (x+2) + 3(x+1)
4x-4 + x+2 + 3x+3
combine all x
4x+x+3x= 8x
combine all numbers without variables
(-4) + 2+3=1
8x+1
