Hey Welsh. Hint solve either by substitution method or elimination

OpenStudy (welshfella):

use elimination 5x + 2y = 7 multiply this by -3 -15x - 6y = -21 ----- (1) -2x + 6y = 9 ------- (2) adding -17x = -12 now find x then you can find y by plugging in this value for x into the first equation and solving for y
