Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.

Combine like terms

4 - x = 24 = 2 + x (add x to both sides of the first equation)2 = x (subtract 2 from both sides of the second equation)

Call your number "x". Write the following:x = 0.484848... 100x = 48.484848... Subtract the first equation from the second equation. This will give you "x" as a fraction. See if you can simplify it.

the first step in solving the equation is to subtract the nine from the three. you will get negative 6.

I will assume the "6" continues indefinitely.You call your number "x", and then: 10x = 46.66666... x = 4.66666... You subtract the second equation from the first, then solve the resulting equation for "x".

A C program to divide, add, multiply and subtract two numbers; #include int main() { int first, second, add, subtract, multiply; float divide; printf("Enter two integersn"); scanf("%d%d", &first, &second); add = first + second; subtract = first - second; multiply = first * second; divide = first / (float)second; //typecasting printf("Sum = %dn",add); printf("Difference = %dn",subtract); printf("Multiplication = %dn",multiply); printf("Division = %.2fn",divide); return 0; }

Subtract 1 form both sides of the equation

2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3

First you need to add a zero to 7.6. Second you subtract 20.39-7.60 and your answer will be 12.79
