Put 12 over 49 then multiply 12x9 then under that put a 0 then do 12x4
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
x = 3

There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
There are several ways to solve x2-x-12. The easiest way, if you have a graphing calculator, is to put y = x2-x-12 and y = 0 into the graph and then solve for the intercepts. A way to do it without a graphing calculator is by factoring. x2-x-12 factors into (x-4) and (x+3). Then set (x-4) and (x+3) each equal to zero and solve. (x-4)=0 becomes x=4. (x+3)=0 becomes -3. Therefore, the answers are -3 and 4.
12 x 49 is solved by Long Multiplication. 49 x12 490 ( 49 x 10 = 490_ +98 (49 x 2 = 98) 588 ==== The answer NB Remember 10 + 2 = 12 As the multiplicand Hence you add the sub=products ( 490 + 98 = 588) to arrive at the correct answer.!!!!!

To solve 49 x 9, you can use the distributive property. Break down 49 into 40 and 9, then calculate: (40 x 9) + (9 x 9) = 360 + 81 = 441. Alternatively, you can simply multiply directly: 49 x 9 = 441.
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
12 x 49 = 588
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7
it is 30,576
12 x 212= 2544
x = 3
45+4 = 49 49/7=7 7*7=49-4=45 so x=7
