To do b equals 2.4 in two step equations, we need to first isolate the variable b on one side of the equation. To do this, we can undo any operations that have been applied to b. For example, if we had the equation 4b = 9.6, we can divide both sides by 4 to get b = 2.4. Similarly, if we had the equation 4b - 8 = 9.6, we can add 8 to both sides of the equation, then divide both sides by 4 to get b = 2.4. Once we have isolated the variable b on one side of the equation, we can set it equal to 2.4 to solve the equation.
It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.
1 / 4 Let x equal the decimal. Set up two equations such that the digits after the decimal point are identical. 2/4 100x= 214.1414... 1x= 2.1414 3/4 Subtracting the two equations, we have: 99x= 212 4/4 x= 212/99 or 2 14/99
