    Step-by-step explanation:

    y+2=3 (x-1) y=-2x+10 should be written as y + 2 = 3 (x - 1) y = - 2x + 10 or

    y + 2 = 3 (x - 1)

    y = - 2x + 10

    Let's eliminate y temporarily. Substitute - 2x + 10 for y in the first equation, obtaining:

    -2x + 10 + 2 = 3x - 3

    Now combine the x terms on the right and the constants on the left:

    10 + 2 + 3 = 3x + 2x

    so that

    15 = 5x. Then x must equal 3. Using the second equation, we now find y by substituting 3 for x:

    y = - 2 (3) + 10, or y = 4

    The solution to this system is (3, 4)
