$2x + 2y = 17$ $4x - y = 25$ I already see a variable somewhat isolated, so lets start with finding what y is equal to in the second equation. $4x - y = 25$ $4x = 25 + y$ $4x - 25 = y$ Now that we know what y is equal to, we can input this value into the second equation $2x + 2y = 17$ $2x + 2(4x - 25) = 17$ $2x + 8x - 50 = 17$ Like terms $10x - 50 = 17$ $10x = 67$ $x = \frac{ 67 }{ 10 }$ $x = 6.7$
