To find two numbers that multiply to 40 and add to -13, you can use the numbers -8 and -5. When multiplied, -8 × -5 equals 40, and when added, -8 + -5 equals -13. Thus, the numbers you're looking for are -8 and -5.
y-13= -5 ----> add 13 to both sidesy-13 +13= -5 +13 ----> simplifyy=8
19. Add 3, then add 4, then add 5, then add 6,etc.
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.
They add up to 13
3p - 8 = 13 - 4p : Add 4p to both sides 7p - 8 = 13 : Add 8 to both sides 7p = 21 : Divide both sides by 7 p = 3.
x - 8 = -13 To solve the equation, you can add, subtract, multiply and/or divide as long as you do the same thing to both sides of the equation. In this case, you can add 8 to both sides making it x - 8 + 8 = -13 + 8 x = -5
