Solve the following system of equations. -7x-4y=14 -8x+5y=16

x=-2 and y=0

Step-by-step explanation: Add 4y to both sides, then divide both sides by -7 to get x alone. X=-4/7y-2. Then substitute that in for x in the second part of the problem. -8(-4/7y-2)+5y=16. Distribute to get 67/7y+16=16 and then subtract 16 from both sides. Divide 67/7y by 67/7, so y=0. Substitute y=0 back in so x=-4/7(0)-2 so x=-2.

step-by-step explanation:

a

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
