10 + 4 x 5 = 30 (10 + 4) x 5 = 70
If you mean: 10+4r = 30 then it works out that r = 5
30
10 + 10 + 10 + 5 + 5 +1 = 41.
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
10 or 1 multiplied by ten or 5 multiplied by 2 or 3 plus7 the answer to 5 (five) plus 5 (five) is 10 (ten).
10 + 4 x 5 = 30 (10 + 4) x 5 = 70
100 + ((5 ÷ 7) x 10) - (11 x 8) = 19 and 1/7.
5 plus 3 is 8, multiplied by 7 is 56.
40
If you mean: 10+4r = 30 then it works out that r = 5
10
If you mean: (2x+2)(5x-5) then it is equivalent to 10x^2 -10
30
10 + 10 + 10 + 5 + 5 +1 = 41.
93,000,000 * 1.86 * (10^5) = 1.7298 × 1013
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
