First, set up the equation 9s + 6L = 186 4s + 5L = 127 To use elimination we need to have the value of the s or L be equal and opposite. If we work with the L variable, we can multiply the top equation by 5 and the bottom equation by -6, giving us:  45s + 30L = 930 -24s - 30L = -762 Now add the like terms and you get the following: 21s = 168 s = 8 Plug 8 into either equation and solve for L 4s + 5L = 127 4(8) + 5L = 127 32 + 5L = 127 5L = 95 L = 19 s=8, L=19
