Solve these simultaneous equations (1) 12x + 3.5y = 32 (2) 8x + 3y = 24

Make the like terms equate by multiplying (1)*2 and (2)*3, ((1)*2) 24x+7y=64, ((2)*3) 24x+9y=72, Take one away from the other to remove the x term and solve for y, (24x+9y=72) - (24x+7y=64), 2y=8 y=4, Substitute y into one of the original equations to find x, 8x+3(4)=24, 8x=12 x=1.5, x=1.5 and y=4
