To solve the equation 7x = 2x, where x represents the unknown variable, you would first subtract 2x from both sides to isolate x. This leaves you with 5x = 0. Then, dividing both sides by 5 gives you x = 0. Therefore, the value of the blank that satisfies the equation 7 times blank equals 2 times blank is 0.

Blank = zero.
2 × ? × 5 = 70 → 2 × 5 × ? = 70 → 10 × ? = 70 → (10 ÷ 10) × ? = 70 ÷ 10 → ? = 7 → The blank is 7.
7 times 2 times 4 equals 56.
7 times 1 equals 7, 3.5 x 2 = 7 etc.
-7 * 2 or -2 * 7
3*7 = 21
