7x + 4y = 5

x - 6y = -19---> x = 6y - 19 {added 6y to both sides}

7x + 4y = 5 {top equation}

7(6y - 19) + 4y = 5 {substituted 6y - 19, in for x, into top equation}

42y - 133 + 4y = 5 {used distributive property}

46y - 133 = 5 {combined like terms}

46y = 138 {added 133 to both sides}

y = 3 {divided both sides by 46}

x = 6y - 19

x = 6(3) - 19 {substituted 3, in for y, into 6y - 19}

x = 18 - 19 {multiplied 6 by 3}

x = -1 {subtracted 18 - 19}

**x = -1 and y = 3
