To solve this system of equations using the combination method, what could you multiply each equation by to cancel out the x-variable? a: 5x−2y=10 b: 4x+3y=7 question 1 options: multiply a by -4 and b by 5 multiply a by 4 and b by 3 multiply a by -3 and b by 2 multiply a by 3 and b by 2

Since you want to cancel x-terms, you're only concerned with the x-term coefficients, 5 and 4. You will want to use the opposite of one of these. It usually works well to multiply the equation with the least y-coefficient by the negative multiplier. That is ...

  Multiply A by -4 and B by 5.
