That's pretty easy. Just add the like terms (2x and 32x) and keep the 3. You get 34x plus 3.
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
If you mean: 32x-3x+1 then it can be simplified to 29x-1
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13

2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
13 + 2x = 32x = 3 - 132x = -10x = -5
3(10x + y) + 2x + 7y (multiply the 3 through the parentheses then combine like terms) = 30x + 3y + 2x + 7y = 32x + 10 y Evaluate an expression for some values of x and y, means to substitute those values into the expression, such that when x = 3 and y = 1 the value of the given expression is 106: 32x + 10y = 32(3) + 10(1) = 96 + 10 = 106
If you mean: 32x-3x+1 then it can be simplified to 29x-1
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
2x - 3y = 3 ------ Eq.1 multiply this by -55x - 4y = 4 ------ Eq.2 multiply rhis by 2_____________________________________ the result after multiply both equation-5 ( 2x - 3y = 3 )2 ( 5x - 4y = 4 )_________________-10x + 15y = -1510x - 8y = 8_________________ by using the elimination method the result will be7y = -7y = -7/7 ,,,,,,,,,,, Y = -1to find the value of X, put the value of Y in Eq.1 :2x - 3y = 32x - 3(-1) = 32x + 3 = 32x = zero ,,,,,,,,,,, X = Zero

I read that as: (3) x (32x) x (3-2) - (32x) x (3) = 32x(3 x 3-2 - 3) = 32x (3-1 - 3) = 32x-1(1 - 32) = -8 x 32x-1 When multiplying the same base (number) to any power, keep the base and add the powers, eg: 32x x 3-1 = 32x + (-1) = 32x-1 3 x 3-2 = 31 x 3-2 = 31-2 = 3-1
2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
if:y = -2x + 3then:if y = 0:0 = -2x + 32x = 3x = 3/2if x = 0:y = -2(0) + 3y = 3So the x-intercept is at {0, 3}, and the y-intercept is at {3/2, 0}
