5x - 3 + 2x + 7 = ?7x + 5 = ?
5x + 2x + 6 = 48 7x + 6 = 48 ....Because you simplify 5x + 2x 7x = 42 ....Because you subtract 6 from both sides to help isolate x x = 6 ....Because you divide both sides by 7 to isolate the x.
5x + 2x - 7 = 0 Simplify 7x - 7 = 0 Add 7 to both sides 7x - 7 + 7 = 0 + 7 7x = 7 divide both sides by 7 x=1
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
i will simplify: 5 times x times 6= 7 times x - 16
5x - 3 + 2x + 7 = ?7x + 5 = ?
x(5x + 7)
5x + 2x + 6 = 48 7x + 6 = 48 ....Because you simplify 5x + 2x 7x = 42 ....Because you subtract 6 from both sides to help isolate x x = 6 ....Because you divide both sides by 7 to isolate the x.
5x + 2x - 7 = 0 Simplify 7x - 7 = 0 Add 7 to both sides 7x - 7 + 7 = 0 + 7 7x = 7 divide both sides by 7 x=1
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
i will simplify: 5 times x times 6= 7 times x - 16
2x + 5x = 35 7x = 35 divide each side by 7 x = 5
2x + 5x + 3 = 9 The two and the five can be added together because they are multiplied by the same term 7x + 3 = 9 Subtract both sides of the equation by three 7x = 6 Divide both sides by seven x = 6/7
2x + 5x = 35 7x = 35 x = 35/7 x = 5
7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
