×-2=10 ==> x = 10+2 = 12
×+3=10 ==> x = 10-3 = 7
×+3=10 ==> x = 10-3 = 7
×+9=18 ==> x = 18-9 = 9
7×+5=68-2× ==> 7x+2x = 68-5 ==>9x = 63 ==> x = 7
8×-9=2×+11 ==> 8x-2x = 11+9 ==>6x = 20 ==> x = 20/6
3y-8=13 ==> 3y = 13+8 ==> 3y = 21 ==> y = 7
×+3=10 ==> x = 10-3 = 7
×+3=10 ==> x = 10-3 = 7
×+9=18 ==> x = 18-9 = 9
7×+5=68-2× ==> 7x+2x = 68-5 ==>9x = 63 ==> x = 7
