5y-14=2y-2 solve for y and show work plz

MrMuchimi

Answer:

y=4

Step-by-step explanation:

Let's solve your equation step-by-step.

5y−14=2y−2

Step 1: Subtract 2y from both sides.

5y−14−2y=2y−2−2y

3y−14=−2

Step 2: Add 14 to both sides.

3y−14+14=−2+14

3y=12

Step 3: Divide both sides by 3.

3y/3=12/3

y=4

3x+10, x^2+4x-2 solve the system.

azamat

Answer:

(-4,-2) and (3,19)

Step-by-step explanation:

We want to solve the system:

$y = 3x + 10$

$y = {x}^{2} + 4x - 2$

We equate the right hand sides:

${x}^{2} + 4x - 2 = 3x + 10$

Rewrite is standard quadratic form.

${x}^{2} + 4x - 3 x - 2 - 10 = 0$

This simplifies to:

${x}^{2} + x - 12= 0$

We factor:

$(x - 3)(x + 4) = 0$

$x = 3 \: or \: x = - 4$

When x=3,

$y = 3 \times 3 + 10 = 19$

Hence a solution is (3,19)

When x=-4,

$y = 3 \times - 4 + 10 = - 2$

Another solution is (-4,-2)
